Integrated Ir Cut Filter - Basler acA2040-55 User Manual

AW00123409000
After conversion to the YCbCr color model is complete, the pixel data is transmitted to the host
computer.
Mono Format
Most cameras equipped with a Bayer pattern color filter can output monochrome images based on
pixel data in the Mono 8 format.
When a color camera is set for Mono 8, the pixel values in each captured image are first
demosaiced and converted to the YCbCr color model as described above. The camera then
transmits the 8 bit Y value for each pixel to the host computer. In the YCbCr color model, the Y
component for each pixel represents a brightness value. This brightness value can be considered
as equivalent to the value that would be sent from a pixel in a monochrome camera. So in essence,
when a color camera is set for Mono 8, it outputs an 8 bit monochrome image. (This type of output
is sometimes referred to as "Y Mono 8".)

7.14.2 Integrated IR Cut Filter

All color camera models are equipped with an IR-cut filter as standard equipment. The filter is
mounted in a filter holder located in the cylindric housing extension of the camera.
Monochrome cameras include a filter holder in the cylindric housing extension of the camera, but
the holder is not populated with an IR-cut filter.
NOTICE
On all cameras, the lens thread length is limited.
All cameras (mono and color) are equipped with a plastic filter holder located in the cylindric
housing extension of the camera.
The location of the filter holder limits the length of the threads on any lens you use with the
camera. If a lens with a very long thread length is used, the filter holder or the lens mount will be
damaged or destroyed and the camera will no longer operate.
For more information about the location of the IR cut filter in the camera, see Section 1.6.2 on
page 42.
